10 protons, 10 neutrons, 12 electrons
A neutral atom of neon with atomic number 10 has 10 protons and 10 electrons. The mass number of 22 indicates the total number of protons and neutrons combined. Since the atomic number is 10, the number of neutrons is 22 - 10 = 12.
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
In a neutral atom of 243Am (Americium), there are 95 protons (which corresponds to its atomic number), approximately 148 neutrons (which can be calculated by subtracting the atomic number from the atomic mass), and 95 electrons (equal to the number of protons in a neutral atom).
A neutral atom of nitrogen-14 has 7 protons, 7 electrons, and 7 neutrons. This is because the atomic number of nitrogen is 7, so it has 7 protons and 7 electrons to maintain neutrality. The atomic mass of nitrogen-14 is 14, which includes the 7 protons and 7 neutrons.
A nitrogen-15 atom has 7 protons, 8 neutrons, and 7 electrons. This is because the atomic number of nitrogen is 7, which corresponds to the number of protons, and the atomic mass of nitrogen-15 is 15, which is the sum of the protons and neutrons. Thus, the number of electrons is equal to the number of protons in a neutral atom.
Rubidium's atomic number is 37 and atomic number is the same as the protons (37 protons) Protons equal electrons so there is the same number of protons and electrons (37 electrons). The atomic mass of this element is About 85, and protons and neutrons weigh about 1 so you can subtract 37 from 85 to get and 48 neutrons. 37 protons, 37 electrons and 48 neutrons.
Bromine has the atomic number 35, so it has 35 protons. To find the number of neutrons in Bromine-80, subtract the atomic number from the atomic mass: 80 (atomic mass) - 35 (protons) = 45 neutrons. Since it is a neutral atom, the number of protons and electrons are the same, so there are 35 electrons.
In a neutral atom of 243Am (Americium), there are 95 protons (which corresponds to its atomic number), approximately 148 neutrons (which can be calculated by subtracting the atomic number from the atomic mass), and 95 electrons (equal to the number of protons in a neutral atom).
Atomic mass refers to the mass of an atom of a chemical element, which is the sum of the number of protons and neutrons in the nucleus. On the other hand, molecular mass refers to the sum of the atomic masses of all the atoms in a molecule, including the contributions from electrons. In general, atomic mass is specific to individual atoms, while molecular mass relates to groups of atoms bonded together.
Carbon
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
A neutral atom of nitrogen-14 has 7 protons, 7 electrons, and 7 neutrons. This is because the atomic number of nitrogen is 7, so it has 7 protons and 7 electrons to maintain neutrality. The atomic mass of nitrogen-14 is 14, which includes the 7 protons and 7 neutrons.
A nitrogen-15 atom has 7 protons, 8 neutrons, and 7 electrons. This is because the atomic number of nitrogen is 7, which corresponds to the number of protons, and the atomic mass of nitrogen-15 is 15, which is the sum of the protons and neutrons. Thus, the number of electrons is equal to the number of protons in a neutral atom.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
Rubidium's atomic number is 37 and atomic number is the same as the protons (37 protons) Protons equal electrons so there is the same number of protons and electrons (37 electrons). The atomic mass of this element is About 85, and protons and neutrons weigh about 1 so you can subtract 37 from 85 to get and 48 neutrons. 37 protons, 37 electrons and 48 neutrons.
All elements on the periodic table are neutral because they have the same number of electrons as protons. Protons carry a positive charge, while electrons carry a negative charge, and having an equal number of each results in a neutral charge overall.
An atom with an atomic number of 50 has 50 protons and 50 electrons. To find the number of neutrons, subtract the atomic number from the mass number: 125 (mass number) - 50 (atomic number) = 75 neutrons.
